People know Robert E. Lee as the Confederate general. Almost nobody knows the 30 years that came before, and it's a wild resume. He shows up at West Point in 1825 and graduates 2nd in his class of 46 with zero demerits in four years. Not one. That basically never happens. Then the Army makes him an engineer. In the late 1830s the Mississippi River was shifting course and threatening to strand the St. Louis harbor on dry land. They send a young Lee. He builds a system of dikes to force the river to scour its own channel, and he saves the port. The city that would later sit in a war he fought against owed its harbor to him. The Mexican War is where he becomes a legend. He isn't leading charges, he's the guy crawling on his stomach through lava fields and enemy lines to find the paths nobody else can find. At Cerro Gordo he scouts a route around the Mexican flank that wins the battle. Winfield Scott, the top general in the country, flat out called him "the very best soldier I ever saw in the field." He runs West Point as superintendent. He chases Comanches in Texas with the cavalry. And in 1859 when John Brown seizes the arsenal at Harpers Ferry, the officer the government sends to end it is Lee. He takes it back in under three minutes. Then in 1861 Lincoln's people offer him command of the entire Union army. He turns it down and goes home to Virginia. History remembers the choice. It forgets the man they were fighting so hard to keep.
